How Long Does a Water Heater Last? (Lifespan of Gas, Electric, Tankless)
It’s important to understand how long a water heater should last when shopping for a new one or when considering upgrading your existing one.The answer is more complicated than it appears at first glance, since there are a lot of elements at play in this situation.Our goal in writing this post is to educate our readers on the typical life of water heaters, how to extend their lifespans, and how to identify if they require a replacement water heater.
Average Lifespan of Hot Water Heaters Compared
|Type of Water Heater||Average Life Span of Water Heater|
|Tank Gas||8 to 12|
|Tank Electric||10 to 15|
|Tankless Gas||20 years|
|Tankless Electric||20 years|
How Long Do Gas Water Heaters Last?
Consider the lifespan of a traditional gas water heater, which is around 10 years.The average lifespan of these sorts of heaters is between 8 and 12 years.The corrosion that occurs in a gas water heater is the most typical cause of failure.
- The heater is equipped with an anode rod, which serves to preserve the inside lining.
- Through electrolysis, the rod draws corrosive particles to itself.
- After a period of time, the rod itself gets too rusted to be able to attract particles any more.
- Instead, the particles sink to the bottom of the tank and begin to eat away at the tank’s lining, causing it to collapse.
- This makes it impossible for the hot water tank to perform its function.
How Long Do Electric Water Heaters Last?
At roughly 10-15 years, the typical life expectancy of an electric water heater is just a few years longer than that of a gas water heater on the market.The two types of water heaters operate in a remarkably similar manner.It is true that the sole difference between an electric system and a gas system is that the water in an electric system is heated by upper and lower heating elements that extend into the tank.
- In a gas heater, the water is heated from below by means of a gas burner.
- The lifespan of an electric water heater is similar to that of a gas water heater in that it is reliant on regular maintenance and the replacement of broken elements.
- It usually has to be replaced if a significant amount of silt has accumulated at the bottom of the tank.
- It is possible to rid the tank of this sediment as early as feasible.
- As the tank matures, however, the effectiveness of this process diminishes significantly.
How Long Does a Tankless Water Heater Last?
Traditional water heaters are those that include a tank and run on either gas or electricity.They can be either gas or electricity-powered.More recent versions do not have a tank at all.
- So, how long do tankless water heaters survive in the field of service?
- As you can see in the table above, tankless water heaters (as well as conventional heaters) are available in two different power options: natural gas or electricity.
- Unlike traditional heaters, however, there is no variation in the lifespan of tankless gas and tankless electric water heaters compared to traditional heaters.
- In both circumstances, they have a lifespan of around 20 years.
- With regular maintenance, however, they may provide you with hot water for an extended period of time – even up to 30 years!
The change in design is the cause for the increased life expectancy of tankless water heaters compared to conventional water heaters.The term implies that a tankless water heater does not store hot water; rather, it only gets hot water when the hot water faucet is switched on.Leaks in the heat exchanger of a tankless water heater might develop over time due to corrosion.
If this results in corrosion, you’ll need to replace the component.Fortunately, these leaks don’t usually occur until a water heater has been in service for at least 15 years.
Which Type of Heater Is the Most Reliable?
Knowing the answer to the question ″how long do water heaters last?″ does not provide you with a complete picture of which model of water heater is the best.Furthermore, you must understand the most dependable type of water heater – which water heater will offer you with the greatest service over the long haul?The answer to this question may vary depending on your requirements and the benefits you want to obtain from your water heater.
Amount of Water Heated
When it comes to providing the same volume of hot water, tank and tankless water heaters are both capable of doing so.When you have a tank-style water heater, the exact amount of water that it will offer you with is determined by the size of your tank.It is critical to select the suitable size for your family’s requirements.
- When it comes to huge volumes of water, gas tank water heaters are preferable than electric tank water heaters since they can heat significantly more water every hour.
- Tankless water heaters, on the other hand, heat water only when it is needed.
- In order to understand how much hot water can be generated at one time by a tankless water heater, you must first look at the GPM capabilities of the particular water heater.
- Overall, tankless water heaters are preferable for this application because, unlike tank water heaters, they continually generate hot water at the GPM rate that they are capable of producing.
- When using a tank model, you will run out of hot water once you have used up all of the hot water contained in the tank.
If you acquire a tankless water heater with a high GPM capability, it will be able to provide the same quantity of warm water as a conventional tank water heater.
The most significant problem with having hot water available at all times is heat loss.Both types of tank water heaters are affected, although tankless heaters are not affected in any way by this phenomenon.Even while you may alleviate the problem to some extent by adding insulation to the tank, there will still be some heat loss from the tank.
- In general, tankless water heaters perform better in this standard than traditional tank water heaters.
Hot Water During a Power Outage
During a power outage, both tank and tankless gas water heaters may keep you warm by supplying you with hot water.If you live in a location where electricity interruptions occur on a regular basis rather than just rarely, this can be a significant advantage.It will ensure that you have constant and dependable access to hot water.
- All things considered, any form of gas-powered water heater is the most appropriate for this use.
Low Risk of Accidents
When water heaters are not maintained on a regular basis, they are susceptible to damage and wear.Some sorts of accidents, on the other hand, are far more serious than others.For example, gas heaters provide the greatest danger since a gas leak in the heater or a pipe might result in an explosion.
- Water leaks can occur in the storage tanks of classic heaters (whether they are powered by gas or electricity).
- Corrosion can manifest itself in a variety of ways, ranging from a minor leak to a significant volume of water escaping.
- This might result in a flood if your water heater is located inside your home.
- Because of these two factors, tankless electric water heaters are the most dependable in terms of safety and dependability.
Fast Heating Capabilities
With a tankless water heater, you will have hot water available immediately when you turn on the tap.Having hot water available in a storage tank, on the other hand, eliminates the need to wait for the water to heat up.The issues only arise when the hot water supply in a tank is depleted, and it might take a long time for the tank to be replenished.
- In comparison to gas heaters, electric heaters take longer to refuel their tanks.
- Overall, gas tankless water heaters are the most efficient and dependable when it comes to providing the fastest heating capabilities.
Using Multiple Sources of Water
If numerous people of your home require access to hot water at the same time, a tankless water heater with a lower power rating may prove to be unreliable in this situation.Consider the following scenario: even if you have more than one shower in your house, you may still discover that only one person can shower at a time if your heater is not sized right.While washing laundry with hot water, you may also want to avoid showering in order to prevent being hit with an unexpected rush of cold water, which may be dangerous.
- That being said, if you pick a tankless water heater with the appropriate GPM for your family, this should not be a problem, and a tankless heater can perform even better than a traditional unit when used with numerous sources of water, as previously stated.
Need for Repairs
Tank water heaters are less complicated to install than tankless water heaters.This can frequently result in a reduction in the demand for repairs and other sorts of maintenance.Furthermore, when repairs are required for a traditional heater, the location of the problem is usually evident, resulting in the problem being resolved in a shorter amount of time.
- Traditional tank versions are easier to fix because of their simplicity, but tankless water heaters are more durable and may not require as many repairs because of their extended life span.
How to Expand Your Water Heater Lifespan
When discussing how long do hot water tanks survive, we’ve brought up the subject of maintenance a few times.Adequate, regular maintenance is vital for any water heater, regardless of brand or model.It might mean the difference between having to replace the heater immediately after the warranty expires and being able to maintain it for several more years.
- There are a few simple things you can take to ensure that your water heater is in peak operating condition.
- It’s important to remember that all of the steps below necessitate shutting off the water heater first and exercising caution since the water you discharge may be scalding hot.
- If you are unfamiliar with working with water heaters, we always recommend contacting with a reputable water heater specialist for any service and repair difficulties.
- We’ll guide you through the process of determining which tankless water heater is best for your particular water scenario in the section below.
1. Check the Pressure-Relief Valve
A pressure-relief valve is included with conventional water heaters.This is intended to prevent pressure from building up inside the tank and resulting in an explosion in the tank.However, it will only be effective in preventing an explosion if it is functioning properly at the time.
- To ensure that it is operating properly on a regular basis, you should check it on a regular basis.
- Prepare by placing a bucket beneath the discharge pipe and running the testing procedure.
- Then, with the pressure-relief valve lever raised, the pressure will be relieved.
- It should be possible to see water coming out of the pipe.
- The valve must be replaced if none of the others work.
2. Take a Look at the Anode Rod
Anode rod corrosion has previously been discussed as a key cause of tank water heater failures in the previous section.Checking to see that your anode rod is in excellent working order is a simple approach to extend the life of your hot water heating system.The rod that is screwed to the top of your tank gas or electric heater may be found here.
- If there is any evidence of corrosion, the rod should be replaced immediately.
- Consequently, there will be no leaks in your tank.
- Replacing the anode rod on a regular basis can help extend the usable life of a water heater by as much as 12 years.
3. Remove Limescale
Even a little quantity of limescale can impair the efficiency of your water heater’s heating element.Limescale accumulation may be easily removed from your heater by rinsing it with pure white vinegar after each use.Depending on whether you have a tank-style or a tankless water heater, the method will be different.
- To prevent a vacuum from forming in a tank water heater, open a faucet just a little bit more than normal.
- After that, connect a hose to the drain valve and cut off the water supply to the house.
- It is necessary to drain some of the water in order to create room for some vinegar.
- After that, you may turn off the water supply valve.
- Remove the anode rod and fill the container with vinegar.
Replacing the anode (and maybe replacing it with a new one, if necessary) and re-connecting the cold water supply are the next steps.Allow at least six hours for the vinegar to work its magic before draining and refilling your tank with water.It is necessary to remove the cover from a tankless water heater as well as close all three water valves.
Remove the purge port valve caps to allow pressure to be released from the heater.Afterwards, connect hoses to each of the valves.Reopen the valves and clean the water heater with vinegar to remove any remaining sediment.Reinstall the valve caps and remove the filter if necessary.Rinse the filter with water and then reinstall it when it has been cleaned.Last but not least, reinstall the lid and turn on your heater.
Detailed instructions on how to do this task safely may be found in your manufacturer’s handbook.
4. Flush Out Sediments
Tank water heaters should be flushed once or twice a year, depending on their size.This eliminates any silt that may have accumulated at the bottom of the tank.Continue to flush the water until there is no sediment remaining – this should take around 2 to 3 liters of water.
- If you continue to clean your tank but there is still sediment present or if the water has a rust tint to it, it is likely that your heater is no longer operating in a safe manner.
- The item in question must be replaced as quickly as feasible in this instance.
- Noises coming from your water heater are another sign that you need to replace it.
- After you’ve flushed the tank, you should no longer see them.
- If they continue, it is likely that there is a significant problem with your heater.
5. Inspect the Gas Lines
Any type of gas water heater (regardless of the brand) requires regular inspection of the pipes. Look for evidence of corrosion as well as fissures in the metal. If you feel that you have a leak, you should contact a professional HVAC service right once. Even a minor leak has the potential to be exceedingly destructive.
6. Look for Water Leaks
If your water heater is located outside, it is possible that you will not discover that it is leaking.Broken or cracked piping in the heater, as well as a puddle beneath the heater on the floor, indicate significant damage and the need for a replacement.Keep in mind that the first time you use a gas heater, there will be some condensation on the surface.
- It’s possible that a tiny amount of water has accumulated in the drain pan.
- This is typical – the water will disappear as soon as the heater reaches the proper temperature, which will be shortly.
- This article has provided answers to two questions: how long do water heaters last and how can you extend the life of your water heater’s tank.
- With this knowledge, you’ll be able to select the most appropriate model of water heater for your household and extend the lifespan of your water heater.
- Before making a purchase, make sure to read our assessment of the best tankless water heaters.

Q. We just bought a house, and the previous owners told us that the water heater is about 6 years old. Does that mean we’ll have to replace it soon? How long do water heaters last?
A.As long as it’s still heating water adequately and making no unusual noises, you should be able to get a few more years of use out of it.The usable life of a water heater varies based on the kind of water heater, the quality of the device, and how well it has been maintained.
- When it comes to water heaters, you may be thinking, ″How long do they last?″ Continue reading to learn about the indications of aging and what to consider when replacing an old water heater.
A Water Heater’s Life Expectancy
There are a variety of elements that influence the life expectancy of a water heater.In addition to the age of the water heater and whether or not it receives regular maintenance, the quality of the water and the amount of water that is used on a regular basis have an impact on its longevity.However, while a water heater may be able to outlive normal projections, there are expectations for how long a water heater will survive dependent on the type of water heater used.
A traditional tank-type water heater lasts an average of 8 to 12 years.
An anode rod is installed within the tank to preserve the internal lining by drawing all corrosive particles to itself through a process known as electrolysis, which is performed on the rod.The particles from the rod’s corrosion accumulate in the bottom of the water tank, where they may ultimately degrade or damage the tank’s lining.When this occurs, the rod is no longer effective at its task.
- Once corrosion begins to occur within the tank, the water heater has reached the end of its useful life.

A tankless water heater can last up to 20 years, sometimes even longer.
Known as ″on-demand″ water heaters, these appliances do not operate continually to ensure a constant supply of hot water, allowing them to survive far longer than their tank-style counterparts in the process.Tankless water heaters (which do not employ anode rods) may, at some point, succumb to corrosion and require replacement of their components.Istockphoto.com has a great list of the best tankless water heaters for 2021.
Your existing water heater’s serial number holds the clue to its age.
The serial number of your water heater, which consists of a letter followed by a series of numbers and is situated on the upper section of the water heater, can help you establish when it was made even if you can’t locate the original documentation for your appliance at the time of purchase.Typically, the letter represents the month—for example, ″A″ represents January, ″B″ represents February, and so on, up to ″L″ representing December—and the next two digits represent the year it was created.For example, a serial number that begins with ″A10″ indicates that it was made in January 2010.

Signs Your Water Heater Might Be on Its Last Legs
- It’s necessary to monitor the performance of your hot water heater on a frequent basis to ensure that it’s operating at peak efficiency. This goes beyond simply following the manufacturer’s maintenance recommendations. If you observe any of the following indicators in your appliance, it’s a good idea to start looking for a replacement right away, even though all appliances have an average lifespan based on normal use. When a water heater is nearing the end of its useful life, it is common to hear banging or rumbling sounds. Few individuals actually follow the manufacturer’s recommendation to flush a tank-style water heater on an annual basis, resulting in calcium buildup from hard water collecting at the bottom of the tank. This is a necessity for maintaining the warranty on the water heater. During usage, the sediment accumulates, hardens, and finally creates a thick crust, which can cause the water heater to creak and bang when it heats the water.
- The hot water has a weird fragrance about it. If the hot water has a strange odor or flavor to it, it is possible that something is polluting the water storage tank. Metal that has been absorbed by the water or bacteria that has gathered inside the tank might be the cause of this odor. Alternatively, if cleaning the tank does not resolve the issue, it may be necessary to hire a plumber.
- Rust might be present in any faucet that produces colored hot water, whether it be red or filthy yellow. It’s critical to evaluate whether the discolouration shows while the cold water is flowing as well as when it’s not. A corrosion problem is more likely to begin inside the water heater rather than within any rusting galvanized pipework, if this is the case
- It is possible that the water temperature will decline. This indicates that the water heater is approaching the end of its service life if the water does not heat up as quickly or does not remain at the correct temperature for as long as it once did
- there is less hot water available than in the past. Over time, silt can accumulate inside the water tank, reducing the amount of space available for water storage within the tank. If the hot water is running out more quickly, it is possible that the tank has to be emptied and cleaned. Waiting too long to clean the tank may result in the tank having to be replaced.
- The presence of water accumulating around the base of a water heater tank is also a bad omen. First, verify sure the leak isn’t coming from a fitting or valve that simply needs to be tightened or replaced by a qualified professional. Engage the services of an expert to investigate the issue and conduct any necessary maintenance. If you discover that the source of the leak is the tank itself, it is possible that the tank is fractured or rusted within.
- The hardness of the water is influencing the quality of the water. Hard water can cause significant damage to a water heater, shortening its service life by two or more years. If you find white limescale accumulating on plumbing surfaces, it is possible that the water heater may need to be changed more frequently.
- The location of the heater might have an impact on its longevity. It takes more energy to heat water in a garage or crawl area since the temperature dips substantially lower there. As a result, water heaters in these locations tend to wear out more rapidly than those in a temperature-controlled home. It is recommended that you begin looking for end-of-life warning indications sooner than the manufacturer suggests if either of these factors applies to your system.
